超空泡航行体纵向运动控制的水洞实验
Water tunnel experiment of longitudinal motion control for supercavitating vehicle
摘要
Abstract
Given that the controller of a supercavitating vehicle designed in an ideal environment can hardly meet the control requirement in actual conditions, an equivalent design method for the longitudinal motional controller of a supercavitating vehicle based on a water tunnel experiment was proposed.In addition, a simulative demonstration was conducted.In the paper, a water tunnel experiment was carried out on the scale model of a supercavitating vehicle with controllable cavitator, and the data of cavitation number and shape of cavity were obtained when a cavitator was moving.Subsequently, the longitudinal motion model of a supercavitating vehicle was amended, and an LPV inversion algorithm was applied to design a controller.Finally, the simulation was applied to inspect the control effect.Results show that a controller design based on water tunnel experiment data was close to the real motion environment, thereby providing an important basis for controlling a supercavitating vehicle in the real environment.关键词
